    Patients with ventricular arrhythmias have lower plasma magnesium levels. Magnesium therapy can normalize electrolyte levels and reduce arrhythmia frequency, as shown by long-term ECG monitoring.

    Area of Science:

    • Cardiology
    • Clinical Biochemistry

    Background:

    • Ventricular arrhythmias are a serious cardiac condition.
    • Electrolyte imbalances, particularly magnesium deficiency, are implicated in arrhythmias.

    Purpose of the Study:

    • To investigate the role of magnesium in ventricular arrhythmias.
    • To evaluate the efficacy of magnesium therapy in patients with ventricular arrhythmias.

    Main Methods:

    • Measured plasma magnesium and erythrocyte electrolyte concentrations (Na, K, Ca, Mg) in patients and controls.
    • Administered intensive magnesium therapy.
    • Monitored changes using long-term ECG recordings.

    Main Results:

    • Patients exhibited lower plasma magnesium and higher erythrocyte sodium and calcium compared to controls.

    Related Experiment Videos

  • Magnesium therapy increased plasma magnesium and altered erythrocyte electrolyte levels.
  • Long-term ECG revealed a quantitative decrease in ventricular arrhythmias following therapy.

    • Conclusions:

    • Hypokalemia and hypomagnesemia are linked to ventricular arrhythmias.
    • Magnesium therapy is effective in managing ventricular arrhythmias by correcting electrolyte imbalances.
